STATES EDWARDoJYQUNG, or nnoLrn ummus, OHIO,AssIGNomrnx ivrnsnninssienm it TO KEX 00., mo, snnours, nrssonn-rwa';co aronam on on-imisson'n e PLUG msnaiii e m an Applicationfiled January This invention relates to self-adjusting, plug inserting devices for use in 'repalrlngf punctures in pneumatic tires orcasings, and the preferred form, of the device lncludes, a hollow tapered piercing tooladapted to be drawn through the pu11cture,-said toel being madein a multiple-number of collapsible portions, between which the stem of a I rubber plug tire patch is compressed and drawn into the opening in the casing.

' The device is simple in construction, inexpensive in its initial'cost," andeificient and practical in use, and also being made in separate parts iseasilykept cleanand free from deposits of cement. v The device comprises the longitudinally divided conical tube, adapted to grasp the stem of the plugbetween its portions,.and a draw means pivotally attached in the smaller ends of these parts.

These sections may have smooth,-eXterna-l surfaces or may be longitudinally corrugated if desired. 7

The invention is hereinafter more fully described, illustrated in the accompanying drawings,

the claims.

In the accompanying drawings Fig l is a'transverse section of a casing showing the tion of the device. Fig. 2 is a side elevation of the tool, showing a looped draw wire pair plugs of mushroom shape, comprising a M pair'of complementary halves forming when 85 I attached; Fig. 3 is an elevation taken at right angles thereto; Fig; 4: is an end plan thereof; Figs. 5 and 6 are side elevations of the preferred form oftool;-"Fig; 7 is an end plan thereof; and Fig. 8 is a perspective of a longitudinally corrugated form; In these views A, represents the tire formed of alternate layers of fabric and rubber. B, B, represent the portions of the tool, which may be halves/for convenience in operation. i

' edges are brought together form hollow, conical, grasping arms, between which the stem 0 of the plugis secured tightly, when 'the tool is drawnthruthe puncture.

Draw means .13, such as a loop of fiexible and specifically pointed out in mode of operation of the plug inserting tool. Fig. 1a is a perspective of one p01" Thetwo portions, when their longitudinal" wir'afigeaee ai to, th se atsb threading l throughf-the eye -formed-ineach part, the parallel straight portions of the wire serving as an elongated draw section and theloopof '5 the wire serving-as a pivot for the parts of .theshell. In this manner the parts of the shell are'also held together, and'lwhen the stem' of theplug isembraced between them, it can be readilydrawn into th'e opening in the tire,and as the she'll 'w'ith"its'enclose'd' 6} stem is drawn through on the exterior side-, U Q

of said casing said pivoted shell parts may I separate or move outwardly out of frictional engagement with said stem, from; which it may be readily removed. V r 657 In F igs; 2 and 3, additional, longitudinal slots F, F, serve to give increasedresiliency v to the parts of the 1001, 0 as to 'grasp thej. 7

. In Fig. 8 the sides of .theparts of the tool 76 are longitudinally corrugatedat G to pro vide additional,'grasping edges. I e

means of this tool, plugs of several izes n be grasped by the same tool, thu V a. d ing to itsadvanta y t p Other modifications of the stru'cturemay be made without departing from thefcharacter of the device, and within the scope of the claims. j r Q Having described ;the invention, what I claim as new and desire .to secure by Letters Patent is: I g L 1. An inserting device for tire-casing rejuxtaposed 'aftapered substantially conical shell within; theinterior of which. the stem of the repair Lplugmay' be engaged, the tip. V ends of said halves being provided with plug sterlnfinto said puncture aperture,.and

thereafter removing said shell outwardly therefrom. I r
